No. 128,606. Patentedlu ly 2,1872.
THOMAS A. EDISON, OF NEWARK, NEW JERSEY.
IMPRQVEWIENT IN PRlNTlNG-TELEGRAPHS.
Specification forming part of Letters Patent No.128,606, dated July 2, 1872.
To all whom it may concern:
Be it known that I, THOMAS A. EDISON, of Newark, in the county of Essex and State of New Jersey, have invented and made an Improvement in Printing-Telegraphs and the following is declared to be a correct description thereof.
In printing-telegraphs considerable time is lost in actuating the stepby-step movement, because there is no opportunity to move the type-wheel more than one letter at a time.
My invention is made to promote rapidity in actuating the type-wheel. Said invention consists in a multiplied motion from a step-by-step movement applied to the type-wheel, so that one pulsation on the line will give a motion to the type-wheel equal to two or more letters. The parts are constructed and arranged so that either the multiplied movement can be given,
' or the single step-by-step motion, according to the letter to be brought into position for print- 111.
in the drawing, Figure 1 is a plan of my instrument, and Fig. 2 is an elevation of the same.
The type-wheel a and figure-wheel b are shown as upon the shaft 0, sustained in suitable frames or bearings d, and I remark that these type-wheels may be of any desired character, and either single or double, and the impression mechanism may be of any available character. The magnet c, armature f, pawl g, ratchet h, and stop t are of any ordinary or desired character, and act to move the typewheel around one letter at a time by a stepby-step movement. The gear-wheel 1, upon the shaft m, takes into the pinion or upon the type-wheel shaft 0, and these two gears are proportioned so that the wheel 1 contains, say, six times the number of teeth in the pinion; thereby the type-Wheel will be revolved six times for one revolution of the shaft m. Upon this shaft on is a ratchet-wheel, p, operated by the pawl r, lever s, armature t, and magnet a. If the ratchet-Wheels h and 1) have the same number of teeth, and the proportion of gearing aforesaid was used, then for each pulsation in the magnet a the type-wheel will move six letters or spaces, and complete a revolution in either four or five pulsations of the magnet 20, according to the number of characters upon such type-wheels. In this manner great rapidity can be obtained, because the long intervals and numerous pulsations required between impressing one letter and the next are lessened. The magnet to may be energized by a reversal of the current operating in the magnet e, or by a separate line-wire. The transmitting dial or instrument may be of any desired character' adapted to these two magnets, and the currents to them.
I claim as my invention- A type-wheel in combination with two actuatin g magnets and connections, substantially as set forth, one for operating a step-bystep motion one letter or division at a time, and the other for moving the type-Wheel two or more letters or divisions at a time, substantially as specified.
Signed by me this 26th day of April, A. D. 1872.
T. A. EDISON.
